The first Calligraphy ink, called Indian Ink or “Encre de Chine”, was invented in Asia in mid-3000 BC. It was a permanent and opaque ink from one of the oldest and most durable pigments: carbon black. From this, Montblanc was inspired to develop the Elixir Calligraphy Collection, a specific permanent ink, perfect for fountain pens.
It contains pure and refined natural dyes from plants and minerals.
Permanent ink contains more solids than other inks, which build up inside the fountain pen over time. The water in the ink, which causes it to flow, evaporates, leaving behind soot and sediment that line the capillary grooves of the ink regulator and the fine capillaries of the piston filling mechanism. For this reason, it is important to clean the fountain pen with lukewarm water after every use of permanent ink to keep it in perfect condition.
